Embodiment 1

[0105] Please refer to the attached figure 1 , and combined with the biological deodorization project of a sewage treatment plant in Hainan Province, the composite filler of the present invention is used as an example, and the present invention is further described in detail.

[0106] The sewage treatment scale of this embodiment is 8000m 3 / d, divided into 2 blocks of 4000m each 3 / d rectangular biochemical reaction pool. Set up two independent biological deodorization filter system devices, one of which is used for odor treatment of biochemical pools, and the other is used for odor treatment of water inlet pump room and sludge dehydration; for the convenience of operation and management, two biological The specifications of the deodorizing filter are the same, and the deodorizing air volume is 3800m 3 / h, the tail gas of the two biological deodorization filters is discharged at a height of 15m through the jointly built wind tower. GB18918) stipulated standards. The deod...

Embodiment 2

[0117] Please refer to the attached figure 1 , and combined with the biological deodorization project of a centralized sewage treatment plant in an industrial park in Fuling, Chongqing, the composite filler of the present invention is used as an example to further describe the present invention in detail. Therefore, this embodiment provides another practical and feasible technical solution that has been successfully used.

Abstract

The invention provides an anti-hardening and acid-corrosion-resistant fluffy biological deodorization composite filler, which is characterized by comprising the following components in percentage by volume: 70-80% of original ecological bamboo charcoal; 1%-2% of plastic hollow sphere / Pall ring; 8%-12% of pine barks, pine scales and / or coconut shell blocks; 2%-3% of light biological ceramsite; and 9%-13% of oyster shell / oyster shell. The composite filler is suitable for attached growth of deodorization microorganisms, raw materials are easy to obtain, wide in source, high in porosity and void ratio, light in weight, small in air resistance, large in biological loading capacity, resistant to microbial acid corrosion and capable of neutralizing acid production, and collapse is reduced after long-term operation; and the deodorization efficiency is high, the service life is long, supplementation is easy in the later period, the autonomy of a user is high, carbon is low, energy is saved, the use cost is low, and the cost performance is high.

Description

technical field [0001] The invention belongs to the technical field of deodorizing fillers, in particular to the technical field of fillers for malodorous gas microbial deodorization filters / towers, in particular to an anti-hardening and acid-corrosion-resistant fluffy biological deodorization composite filler. Background technique [0002] Odor pollutants refer to gaseous substances that stimulate the sense of smell, cause unpleasantness and damage the living environment. Odor pollution is widely distributed and has a wide range of influence, for example, in sewage lifting pump stations, grill rooms, aerated grit chambers, primary sedimentation tanks, anaerobic biochemical tanks, etc. in the process of sewage treatment; in the process of sludge treatment Sludge concentration, dehydration and drying, transfer and other links; in the process of composting, sanitary landfill, high-temperature incineration, cleaning and transportation, etc. in the process of garbage treatment; ...
